Speaking of IDI's, anyone here had any experience with them? I think the next horse I'll add to the stable is something I'd feel a lot better about running waste oil through. A new IP and sticks are CHEAP for them

If taken care of and left stock.....they're 2/300k engines at best. As mentioned they do eat head gaskets but usually because someone ignores either a water leak or has the pump turned up working the crap out of it. They eat glow plugs and relays as well.....probably mostly because the aftermarket stuff stuff sucks that bad. Then there's the ever leaking top hat fuel returns on the injectors...what an absolute schit idea.

If I find one in a truck I want.....I'd run it till I had the smallest of issues then pull it in favor of a 6bt.

I think the p pump is as good as it gets if wanting to run used oil etc. I've been thinking of putting a greaasecar setup or something similar in the 96, as I've been chucking around 12-15 gallons of used canola oil in the dumpster on a weekly basis for over a year at my job. That would cover over 90% of my spring/summer/fall driving costs. At about $220 per tank of fuel, it'd pay for itself in 9-10 tanks of fuel lol. I agree with ellis, if you find a nice ford run it till it pukes and throw the 7.3 in the garbage where it belongs.

It's more about the sheer size and strength of the "6 cylinder" p7100 and it's pumping abilities. A VE can do it too, but I'd imagine it's less forgiving pumping a cold thick fluid at higher hp levels. if one accidently did so.
